* An original anime based on an idea by Kawamori Shouji and inspired by the all-female idol group AKB48.

During an age when public entertainment was outlawed, an idol group holds guerrilla concerts without any concern for dangers.

In
the beginning of the 21st century, a world war broke out amongst
mankind. In the aftermath of the war started by humanity itself, the
earth's ecosystem was irrecoverably affected, and it had no choice but
to escape the now devastated earth to live in space. A new era began
with the Star Calendar 0000. Shortly afterwards entertainment was
prohibited by law and the sacred place for otaku, Akihabara, became the
public entertainment's absolute area of defense and the only place to
perform such activities. In Star Calendar 0048 once more a group was
formed in the hope to resume the legacy of the legendary idol act AKB48,
which continued to shine even during the earth's downfall. With the law
in place they were deemed as an illegal act and unable to hold official
live events. This is when the group's concept changed. Instead of the idols you can meet they became the idols who come to meet you.
Branded as terrorists by authorities they didn't give up and decided to
take up arms to protect the stage they stand on, the fans who cheer for
them and the citizens who are deprived of entertainment.

This is
the tale of those girls who succeeded the famous name and fight for the
freedom of entertainment. Their name is... AKB0048.
